Remote controls
5 Jan 2009 05:07 pmI realised a while ago that IR remote controls seem to have changed.
I remember the first remote control we had for a TV (in the mid-seventies) could be pointed anywhere in the room (or sometimes even into the kitchen if you pointed it through the wide open door and stood to the side so the signal could bounce properly) and it would change the channel, while most modern ones need to be pointed directly at the device to work.
Has anyone else noticed this? Was this a different system? The old one was definitely IR, too. Maybe the beam is weaker and tighter focussed or something.
